1,427,371. Application filed August 8,

To all whom it may concern: Be it known that LEnNnsr GLASS,V2L citi? zen of the United States, residing at Reading,- in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in a Gearing and. I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable .others skilled in the art" to which it appertains to make and usethe same. s This invention relates to gearing where by an intermittent reverse rotary movement is converted into a continuousrotary movement in either a clockwise or counterclockwise direction as desired. Y Specifically considered the invention 're-' lates to an improvement in the gearing disclosed in U. S; Patent No. 15378 781 granted me the 21st day of May, 1921, fora rotary tooth brush. o The present invention simplifies the gearing disclosed in my'prior patent and renders the same morepositive and certain in action. o Other objects and advantages will be apparent and suggest themselves as the na-' ture of the invention isunderstOOd.

While the drawingsillustrate an em-bodiment of the'invention it is to be understood that in adapting the same to meet differ ent' conditions and requirements, various. changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention. 1 I 1 Referring to the accompanying drawings forming a part of the'specification, Figure 1 is a detail view of a rotary tooth brush embodying the invention. 5 Figure 2 is a sectional detail of the easing,the brush being omitted and the parts being shown on a larger scal'e. v Figure 3 is a sectional detail of the gearmel Figure 4 is asection" on the "line as -wo f Fig. 2, and I I Figure 5 is a detail. 5 1

ings by like reference characters. i o

- The numeral 1 designates a suitable frame or casing which constitutes a-housing for the/gearing. A drive shaft 2 is suitably" mounted withingthe housingor frame 1. Agear wheel 8' is fast to the drive shaft 2 and is provided at one side witha hub 4;.

A spiral spring 5 is fast at one end to the hubs and is connectedat itsopposite end to the frame 1 and is adapted to be wound by rotation of the gear wheel'3 inone direction, A tape 6 vor like. element is ,attached at one end to the hub 4 and iswound thereon and extends a through an opening formed in a sideof the frame 1. 5 When the tapeor like-part v6 is drawnupon it isunwound from'thehub 4:1 and impartsrotary movement to the gear wheel. Sand at the s'ame'time tensions-the spring 5 by winding the same .upon the'hub 4. -When ,the tape or like part 6 is relaxed the spring 5 comes into play and rotates the gear wheel311n a reverse direction and rewinds the tape (5 uponthehub 1. A'ring7 or like part is'moun'ted in axial 'alinement with the drive shaft;2 andis providedfat its outer edge with ratchet teeth 8 adaptedto cooperatewith aqdog 9 whereby the ring? is held stationary during the 'rotation of the drive shaft 2 inone direction. The ring 'or part7. is provided with gear elementslO which are in meshing relation with the teeth of the .gear wheel 3. A rotary member :11 isloose on the drive shaft 2 and is provided

k

12 and 13, the teeth 12 being. in mesh with theteeth ofthe gear elements 10 and-the teeth 13 being in meshwith the teethof gear elementsuli and 15 looselymounted upon a driven-shaft 16 which drives the parts to be rotated. The

rotary member 11 is provided upon one side with clutch teeth 17 which cooperate with correspond;

'ing teeth ofia spring actuated clutch mem ber 18 splined to the drive shaft 2. When instrumentality of the clutch member 1'8.

with gear teeth the gear'wheel 3 is rotatediby a direct pull I upon thektape or like part6, the member '11 is correspondinglvrotated through the y o During this movement the ring or part 7 is free to rotate with the parts 3 and 11. Upon a reverse rotation otthe gear wheel 3 and drive shaft 8 under the action of the spring 5, the ring or part 7 1s held stationary by the teeth Sand dog 9 and the gear elements 10 being in mesh with the teeth of the gear wheel 8 are rotated thereby and positively transmit motion to the part 11 inthe same direction. During this action the teeth of the clutch member 18 ride upon the clutch teeth,17., It will thus be understood that the part 11 is continuously rotated in the same direction by an intermittentreverse rotary movement im-,

from the'frame orhousing 1 and iszprovid-,

ed at its outer end with a tooth brush 19 or-otherpart to be rotated. A housing 20 attached tc the frame 1 receives the shaft 16 which ismounted at its outer end therein. The gear elements 14 and '15 are loose on the shaft-16 and each is provided uponits inner side'with clutch teeth121. A. clutch member-22 splined on the shaft 16 is movable between the gear elements 1 f and-15 and isv adapted to be thrown into clutch engagement with either. i A shipper member 23 mounted in the frame. or casingl is in cooperative relation with therclutch member 22 whereby the latter maybe moved to a neutral position or into clutch engagement with either-one of the gear elements 14 or 15 so as to rotate the shaft 16 in the desired direction. The shaft16 may be rotated continuously in a clockwise or counterclockwise direction according to which one of the gear elements M or 15 -is in clutch engagement therewith. A pull upon the tape or part 6 unwinds it from the hub a and rotates the gear 3 inione direction and at the same time winds the spring 5. Th is effects positive rotation of? the member 11 through the clutch 17 and 18. lVhen the part 6' is relaxed the spring 5 comes into play to rotate the gear element 3, in a reverse direction thereby'rewinding the part 6 and positlvely-rotatmg theYgea'r elements 10 whichin turn effect a rotation of the part 11 in the same direction, the clutch 17 and 1S slipping during this action. During the reverse rotation of the gear element 3 the part 7 supporting the gear elements 10 is held stationary hence the action ofthe gear-elements 10' in transmitting. motion from the parts 3 to the parts 11..
